CHS — Oryza sativa Indica Group

Summary

BGIOSGA024263 (symbol CHS, preferred name OiCHS) on chromosome 7 of Indica rice encodes a chalcone synthase, a type III polyketide synthase with chalcone/stilbene synthase and thiolase-like domains. The enzyme exhibits naringenin-chalcone synthase and bisdemethoxycurcumin synthase activities, along with acyltransferase and protein homodimerization activities. This gene is associated with the regulation of flavonoid and polyketide biosynthesis, pigmentation, pollen wall assembly, leaf senescence, and developmental processes. It has been linked to hull color and oxidative stress response. The encoded protein localizes to the endoplasmic reticulum. Studies of related genes in other species connect the family to EC 2.3.1.74 (naringenin-chalcone synthase) and EC 2.3.1.211 (bisdemethoxycurcumin synthase) activities.
